[Show abstract][Hide abstract] ABSTRACT: This study aimed to assess vaccination coverage for novel influenza A (H1N1) in Korea using a immunization registry system as the data source. Vaccination coverage was found to be 26.1% for the total population and 54.4% for priority groups targeted by a national vaccination campaign between October 27, 2009, to March 31, 2010. The factors associated with increased coverage were rapid vaccination and free vaccination; these factors may need to be considered in future pandemics.

[Show abstract][Hide abstract] ABSTRACT: We carried out this study to describe the difference between intention to receive vaccine against influenza A (H1N1) before the vaccination campaign and actual vaccine coverage rate after vaccination campaign; and to find out the factors affecting the acceptability. We analyzed data on intention to receive vaccine against influenza A (H1N1) and actual vaccination coverage rate from IR (immunization registry). In a survey of pre-vaccination, the sample size was 1042 and the survey results were weighted with gender and age distribution for sample distribution to be similar to population distribution. Although the intention to receive vaccine against influenza A (H1N1) was high, the actual vaccination coverage was lower than their intention. The factors affecting their intention were the degree of fear for novel influenza A (H1N1), the possibility to be infected with the virus, priority for production of novel influenza vaccine between timing and safety, and belief for effectiveness of novel influenza vaccine. Besides 2009 influenza A (H1N1) vaccination experience developing to resolve the effecting factors on intentions to receive vaccine, which would be the effective way to prepare for anther pandemic in the future.
[Show abstract][Hide abstract] ABSTRACT: This study establishes the South Korean population-based preference weights for EQ-5D based on values elicited from a representative national sample using the time trade-off (TTO) method.
The data for this paper came from a South Korean EQ-5D valuation study where 1307 representative respondents were invited to participate and a total of 101 health states defined by the EQ-5D descriptive system were directly valued. Both aggregate and individual level modeling were conducted to generate values for all 243 health states defined by EQ-5D. Various regression techniques and model specifications were also examined in order to produce the best fit model. Final model selection was based on minimizing the difference between the observed and estimated value for each health state.
The N3 model yielded the best fit for the observed TTO value at the aggregate level. It had a mean absolute error of 0.029 and only 15 predictions out of 101 had errors exceeding 0.05 in absolute magnitude.
The study successfully establishes South Korean population-based preference weights for the EQ-5D. The value set derived here is based on a representative population sample, limiting the interpolation space and possessing better model performance. Thus, this EQ-5D value set should be given preference for use with the South Korean population.

[Show abstract][Hide abstract] ABSTRACT: Objectives: This study was conducted to understand the status of influenza vaccination in some rural communities and to apply the results to formulate a counterplan for influenza prevention. Methods: The authors conducted a questionnaire survey from May 26 to May 29, 2003 among the residents in two rural communities: 602 people at the village Gigye-myeon and 965 at the village Cheongsong-gun. For statistical analysis the chi-square test and chi-square for trend method were used. Significance was set a p
